I'm in the process of very slowly introducing the cats to outside.

ATM, we just take them outside for 5-15 minutes at a time, under supervision.

How do I get them to go to the toilet outside? I've tried taking their litter tray outside as well as throwing some (biodegradable, paper) litter on the grass and placing them in the general vicinity...

So far they are only interested in eating grass and running next door

Any help would be greatly appreciated

TIA
